• biodegradable
  • The claim is therefore deceptive Since there are no pass-fail tests for "biodegradable" plastic bags, manufacturers must print on the product the environmental requirements for biodegradation to take place, time frame and end results in order to be within US Trade Requirements. (wikipedia.org)
  • In 2007, the State of California essentially made the term "biodegradable bags" illegal, unless such terms are "substantiated by competent and reliable evidence to prevent deceiving or misleading consumers about environmental impact of degradable, compostable, and biodegradable plastic bags, food service ware, and packaging.

  • PAHs
  • Polycyclic aromatic hydrocarbons (PAHs) biodegradation in contaminated sediment is an attractive remediation technique and its success depends on the optimal condition for the PAH-degrading isolates. (biomedcentral.com)
  • The aims of the current study was to isolate and identify PAHs-degrading bacteria from surface sediments of Nayband Bay and to evaluate the efficiency of statistically based experimental design for the optimization of phenanthrene (Phe) and Fluorene (Flu) biodegradation performed by enriched consortium.

  • groundwater
  • This new and innovative remediation technology was developed to stop migrating groundwater contaminant plumes by rapidly reducing contaminant concentrations with a sorptive medium while also enhancing or accelerating microbial-driven biodegradation process. (environmental-expert.com)
  • Initial monitoring conducted during the cooling period indicated that a dissolved plume remained in some portions of the treatment zone at concentrations greater than several thousand μg/L. The ratio of biodegradation daughter products to PCE in groundwater was significantly greater than prior to implementation of ERH. (environmental-expert.com)
  • Plastics
  • The success and dominance of plastics starting in the early 20th century led to environmental concerns regarding its slow decomposition rate after being discarded as trash due to its composition of large molecules. (wikipedia.org)

  • An ongoing study of biodegradation rates of polymers has led to the development of a new ASTM International standard, D7473, Test Method for Weight Attrition of Plastic Materials in the Marine Environment by Open System Aquarium Incubations. (environmental-expert.com)
  • Insights
  • According to a bottled water survey conducted by Perception Research Services International (PRS) for Brand Packaging published in August 2011, where shoppers were interviewed in person to gain some insights on marketing claims, environmental and recycling messages were misunderstood and not even noticed by a majority of consumers interviewed.
